Project description
Solving the mystery of the narwhal tusk
Narwhals are mysterious creatures in the ocean, famous for their long, spiralled tusks. However, scientists still know very little about the purpose or structure of these fascinating features. The tusk’s unique left-handed spiral and incredible length have puzzled researchers for years. Understanding the tusk’s biology could unlock new insights into marine evolution and biomaterials. Supported by the Marie Skłodowska-Curie Actions programme, the HI-Twist project aims to uncover the secrets of the narwhal tusk by using advanced 3D X-ray imaging techniques. Researchers will study the tusk’s nano, micro, and macrostructures to reveal how it is built and its mineral composition. This project could provide a groundbreaking method for studying biological materials.
Objective
Narwhals are mysterious animals that have fascinated humankind since ancient times. They are known for their unique spiralled tusks, which made people believe in the existence of unicorns for centuries. The up to 3 m long straight tusk displayed by males always has a left-hand spiral macrostructure, making it unique in the animal kingdom. Very little is known about these fascinating animals, and the reason, origin and biological structure of their tusk is a great question mark among marine biologists and bio-material scientists. In the proposed project, we will aim to reveal the hierarchical structure and biomineral characteristics of this unique biological material: their tusk. For that purpose, we will employ a combination of recently developed 3D X-ray imaging techniques in a hierarchical approach, studying their nano, micro and macrostructure with X-ray computed tomography, X-ray diffraction and X-ray small angle X-ray scattering. Novel imaging techniques using synchrotron radiation like tensor tomography will reveal the structural organization and anisotropy of the tusk building blocks, and diffraction computed tomography will provide very valuable information about the biomineral phase in the tusk and teeth. The multi-length scale approach explained in this project will be a pioneer in the field and we expect to establish a new methodology for a more complete structural characterization of biological and composite materials. All that will be implemented and developed in the 24 months of the project, which compiles 4 experiments in large-scale synchrotron facilities, data analysis strategies development and the establishment of a complete multiscale model of the narwhal tusk biological structure.
